- Call-second
In
telecommunication , a call-second is a unit used to measurecommunication straffic density."Note 1:" A
call -second is equivalent to 1 call with a duration of 1 second."Note 2:" One user making two 75-second calls is equivalent to two users each making one 75-second call. Each case produces 150 call-seconds of traffic.
"Note 3:" The acronym
CCS (Centum Call Seconds ) is often used to describe 100 call-seconds."Note 4:" 3600 call-seconds = 36 CCS = 1 call-hour.
"Note 5:" 3600 call-seconds per hour = 36 CCS per hour = 1 call-hour per hour = 1 erlang = 1 traffic unit.

Federal Standard 1037C
*MIL-STD-188 In a communication network, it is possible for one channel to carry numerous calls simultaneously by means of multiplexing. In theory, there are many ways in which a channel can carry a particular number of CCS.One call-second is equivalent to one call occupying a channel for one second. Thus, 1 CCS = 100 call-seconds = 1/36 erlang.
